We found the divisors of 815, 836, 81, 982 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 815, 836, 81, 982 is 1.

Therefore, GCD of numbers 815, 836, 81, 982 is 1

Given Input Data is 815, 836, 81, 982

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 815 is 5 x 163

Prime Factorization of 836 is 2 x 2 x 11 x 19

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 982 is 2 x 491

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(815, 836) = 681340

GCD(815, 836) = ( 815 x 836 ) / 681340

GCD(815, 836) = 681340 / 681340

GCD(815, 836) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 982

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 982) = 982

GCD(1, 982) = ( 1 x 982 ) / 982

GCD(1, 982) = 982 / 982

GCD(1, 982) = 1

GCD of 815, 836, 81, 982 is 1
